Introduction - Significant figures and rounding. Ionic strenght. Activity and activity coefficients. Debye-Hückel equation.
Ionic equilibria - Acid-base equilibria (Strong and weak acids and bases. Polyprotic acids. Buffer solutions. Distribution diagrams). Solubility equilibria (Solubilities vs. solubility products. Common ion effect. Ionic strenght vs. solubility. Simultaneous equilibria in precipitation. Simple and complex precipitation). Simultaneous solubility-acidity equilibria (Solubility relation on pH). Complexation equilibria (Review on ligands and chelating agents. Formation and dissociation constants. Ion masking). Simultaneous solubility-complexation and acidity-complexation equilibria (Conditional-formation constants. Replacing reactions). Redox equilibria (Oxidizing and reducing agents. Galvanic cells. Standard redox potentials. Nernst equation. Formal redox potentials).
General methods in quantitative chemical analysis - Gravimetric analysis (Basic principles. Crystalline and colloidal precipitates). Volumetric analysis (Basic principles. Acid-base titrations. Precipitation titrations with Ag+. EDTA titrations. Redox titrations. Calculated values in a titration curve. Equivalence and final titration points. Chemical indicators).
Instrumental quantitative chemical analysis - Electrochemical methods (Potentiometry. Direct potentiometric measurements. Reference electrodes. Indicators electrodes. Glass electrode. Ion-selective electrodes. Calibration line. Added solutions method. Potentiometric titrations.). Spectroscopic methods (Properties of light, absorption and emission of radiation. Transmittance and adsorbance. Lambert-Beer's law. Atomic spectroscopy).
